Download Solution PDFएका वृत्तचितीचे वक्रपृष्ठफळ 484 चौरस सेमी आहे. जर वृत्तचितीची उंची 7 सेमी असेल, तर वृत्तचितीचे घनफळ(क्यूबिक सेमीमध्ये) किती असेल? (π = 22/7 वापरा)
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेले आहे:
वृत्तचितीचे वक्रपृष्ठफळ(CSA) = 484 सेमी2
वृत्तचितीची उंची(h) = 7 सेमी
वापरलेले सूत्र:
वृत्तचितीचे CSA = 2πrh
वृत्तचितीचे घनफळ (V) = πr2h
r = वृत्तचितीच्या पायाची त्रिज्या
गणना:
2πrh = 484
⇒ 2 × \(\dfrac{22}{7}\) × r × 7 = 484
⇒ r = 11
V = πr2h
⇒ V = \(\dfrac{22}{7}\) × 112 × 7
⇒ V = 2662
∴ वृत्तचितीचे घनफळ = 2662 सेमी3
